Evidence of a chemical reaction from the rusting of an iron nail is the formation of brown Iron Oxide. The oxidation of iron is a chemical reaction.
Rust is iron oxide. The presence of rust indicates that the iron in the nail has oxidized, which is a chemical reaction.

The most obvious sign of rusting is a colour change - red-brown patches of iron oxide will appear on the nail.
